Mike, please open a separate bug for you issue with the relevant details
about the Hardware. I am marking this bug Invalid now since the OP has
switched to x86_64 where the bug is not visible anymore.

A similar oom-killer freeze happens to x86_64 laptop with no particular memory
load. It happens only infrequently, although it seems to appear immediately
after an apparmor warning.
% uname -a
Linux ithaca 2.6.27-11-generic #1 SMP Thu Jan 29 19:28:32 UTC 2009 x86_64
GNU/Linux
% cat
We moved the servers to 2.6.24-22-server x86_64 two weeks ago and had no
problem since, while running the same workloads and processes.
